The 5550 PRO Navigation System has a 5-in. LCD screen. It features Junction View with Lane Assist, state mileage log, hours-of-service Log and last-mile routing for road coverage on secondary highways. The Quick-Tabs feature includes navigational details such as the distances to weigh stations, travel centers, rest areas and mile markers, and the unit includes more than 12 million standard points-of-interest and 33,000 truck-specific points-of-interest. It comes with three months of unlimited downloads from Cobra’s AURA Camera & Driving Hazard Database, which alerts drivers to the locations of fixed speed and red-light cameras, dangerous intersections and known speed traps.
